Revision of LED Head Illumination

An LED correcting head, which is capable of correcting the illumination of the LED for each dot, is being
used in this printer. LED illumination correction function of 16 steps is carried out by using an EEPROM
which is installed in the LSI that maintains the LED illumination correction values, and an LED correction
drivers (MSM6731BWAF or MSM6732BWAF) together as a pair.

The LED correcting head consists of the correction control LSI (MSM6730WAF), LED drivers
(MSM6731BWAF or MSM6732BWAF), and an LED array. The block diagram of the LED correcting head
is shown below.

The existing LED head receives the printing data from the CPU directly at its LED drivers. With the LED
correcting head, a correction control LSI (MSM6730WAF) is connected between the CPU and LED
drivers, so the printing data is input to the LED drivers through the correction control LSI. In order to
maintain compatibility with the existing LED head, the printing operation of the LED correcting head is
carried out through identical sequence.

The LED correcting head is a 600 dpi head, with the LED drivers located on both sides of the LED array
with a 300 dpi pitch spacing. The printing and correction data obtained from the CPU through four signal
lines are sent to the LED array.
